An experimental and predictive study has been conducted on the tumbling generating characteristics of a four-valve cylinder head under steady flow conditions. This was conducted on an idealised cylinder head with a disc combustion chamber and two straight axisymmetric intake ports equipped with shrouded valves. The tumbling generating characteristics of each intake configuration were evaluated using a steady flow rig which converted tumble into swirl. Experimental measurements of the swirl and axial velocity distributions for various valve lifts were obtained using laser Doppler anemometry. Theoretical predictions were performed using a commercial computational fluid dynamics (CFD) code. Comparisons have been made between the experimental results and theoretical predictions
